If you want to access your VFP COM object through DCOM you have to pass your data to the client as an ADO RS. If you want to use VFP on the client too, you will have to convert the RS to a cursor on the client end. Some VFP native controls will not bind to ADO RS. One workaround is to use ADO compatible ActiveX controls on your VFP forms, then you won't have to convert to a cursor, or use a VB front end. When your done editing on the client, convert back to ADO RS and marshall changes back to COM object and update server.

All of your validation is still in the middle tier, the front end is just a presentation layer.
